Check Digit Verification of cas no
The CAS Registry Mumber 3950-28-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3950-28:
(6*3)+(5*9)+(4*5)+(3*0)+(2*2)+(1*8)=95
95 % 10 = 5
So 3950-28-5 is a valid CAS Registry Number.

Synthesis of o-Nitroarylamines via Ipso Nucleophilic Substitution of Sulfonic Acids
Manne, Srinivasa Rao,Chandra, Jyoti,Mandal, Bhubaneswar
supporting information, p. 636 - 639 (2019/01/21)
A mild, efficient, and eco-friendly method for the synthesis of o-nitroarylamine from o-nitroaryl sulfonic acid via ipso nucleophilic aryl substitution by amine is described. The products have been obtained with good yields at room temperature without the assistance of any metal, activating agent, or toxic oxidant. This method is useful for racemization-free synthesis of N-aryl amino acid esters.
Circular dichroism, ultraviolet, and proton nuclear magnetic resonance spectroscopic studies of the chiral recognition mechanism of β-cyclodextrin
Purdy, William C.
, p. 1405 - 1412 (2007/10/02)
The chiral recognition mechanism of β-cyclodextrin was studied by UV-visible, circular dichroism, and proton nuclear magnetic resonance spectroscopic methods. The D and L enantiomers of DNP-valine, DNP-leucine, and DNP-methionine were used as model solute
